IWMPControls::previous method
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The previous method sets the previous item in the playlist as the current item.
public void previous();
Public Sub previous()
Implements IWMPControls.previous
This method has no parameters.
This method does not return a value.
If the playlist is on the first entry when previous is invoked, the last entry in the playlist will become the current one.
The following example uses previous to move to the previous item in the current playlist in response to the Click event of a button. The AxWMPLib.AxWindowsMediaPlayer object is represented by the variable named player.
private void previousButton_Click(object o, System.EventArgs args)
{
// To get all of the available functionality of the player controls, cast the
// value returned by player.Ctlcontrols to a WMPLib.IWMPControls3 interface.
WMPLib.IWMPControls3 controls = (WMPLib.IWMPControls3)player.Ctlcontrols;
// Check first to be sure the operation is valid.
if (controls.get_isAvailable("previous"))
{
controls.previous();
}
}
Public Sub previousButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles previousButton.Click
' To get all of the available functionality of the player controls, Dim the
' value returned by player.Ctlcontrols as a WMPLib.IWMPControls3 interface.
Dim controls As WMPLib.IWMPControls3 = player.Ctlcontrols
' Check first to be sure the operation is valid.
If (controls.isAvailable("previous")) Then
controls.previous()
End If
End Sub
